python之为什么 pysqlite 不能正常工作

我尝试安装 pysqlite。安装过程中开始出现一些可疑的东西。为什么我输入:

python setup.py build 

最后我得到了如下信息:

src/module.c:286: error: ‘SQLITE_PRAGMA’ undeclared here (not in a function) 
src/module.c:287: error: ‘SQLITE_READ’ undeclared here (not in a function) 
src/module.c:288: error: ‘SQLITE_SELECT’ undeclared here (not in a function) 
src/module.c:289: error: ‘SQLITE_TRANSACTION’ undeclared here (not in a function) 
src/module.c:290: error: ‘SQLITE_UPDATE’ undeclared here (not in a function) 
src/module.c:291: error: ‘SQLITE_ATTACH’ undeclared here (not in a function) 
src/module.c:292: error: ‘SQLITE_DETACH’ undeclared here (not in a function) 
src/module.c: In function ‘init_sqlite’: 
src/module.c:419: warning: implicit declaration of function ‘sqlite3_libversion’ 
src/module.c:419: warning: passing argument 1 of ‘PyString_FromString’ makes pointer from integer without a cast 
error: command 'gcc' failed with exit status 1 

我只是忽略了最后一行并决定继续。所以，我输入:

python setup.py install 

然后，我又收到了类似的错误消息:

src/module.c:288: error: ‘SQLITE_SELECT’ undeclared here (not in a function) 
src/module.c:289: error: ‘SQLITE_TRANSACTION’ undeclared here (not in a function) 
src/module.c:290: error: ‘SQLITE_UPDATE’ undeclared here (not in a function) 
src/module.c:291: error: ‘SQLITE_ATTACH’ undeclared here (not in a function) 
src/module.c:292: error: ‘SQLITE_DETACH’ undeclared here (not in a function) 
src/module.c: In function ‘init_sqlite’: 
src/module.c:419: warning: implicit declaration of function ‘sqlite3_libversion’ 
src/module.c:419: warning: passing argument 1 of ‘PyString_FromString’ makes pointer from integer without a cast 
error: command 'gcc' failed with exit status 1 

之后我想试试 pysqlite 是否有效。 如果在 python 命令行模式下我输入

from pysqlite2 import * 

Python 不会提示。但是，如果我尝试遵循书中的示例:

from pysqlite2 import dbapi2 as sqlite 

我收到一条错误消息:

Traceback (most recent call last): 
  File "<stdin>", line 1, in <module> 
  File "pysqlite2/dbapi2.py", line 27, in <module> 
    from pysqlite2._sqlite import * 
ImportError: No module named _sqlite 

有没有人知道为什么会发生这种情况以及如何解决这个问题。顺便说一句，我已经安装了新版本的Python。 “python -V”给我“Python 2.6.2”。提前感谢您的帮助。

请您参考如下方法:

I just ignored the last line and decided to continue.

您不能只忽略最后一行。它告诉你有一个错误，所以它无法编译。您运行的下一件事告诉您它无法安装，因为它无法编译。然后，你的 python 告诉你它无法运行代码，因为它没有安装。在继续安装之前，您需要让编译步骤正常工作。
